Honua like me ka honua a puni ke kihi

Ua loaʻa i ka poʻe Astronomers e hana ana ma kahi hui e hoʻohana ana i nā telescopes ESO a me nā mea nānā ʻē aʻe i nā hōʻike maopopo o kahi honua e hoʻopuni ana i ka hōkū kokoke loa i ka ʻōnaehana solar, ʻo Proxima Centauri, "wale nō" ma kahi o ʻehā mau makahiki māmā mai ka Honua.

ʻO Exoplanet, i koho ʻia i kēia manawa Proxima Centavra b, kaʻapuni i ka ʻulaʻula ʻulaʻula maʻalili i nā lā 11,2 a ua ʻike ʻia he ʻano wela o ka ʻili kūpono no ka loaʻa ʻana o ka wai wai. Manaʻo nā kānaka ʻepekema he kūlana kūpono ia no ka puka ʻana a me ka mālama ʻana i ke ola.

ʻO kēia honua hou hoihoi, i kākau ʻia e ka poʻe astronomers ma ka pukana o ʻAukake o ka puke pai Nature, he honua ʻoi aku ka nui ma mua o ka Honua a me ka exoplanet kokoke loa i ʻike ʻia e mākou. ʻO kona hōkū hoʻokipa he 12% wale nō ka nuipaʻa o ka Lā, 0,1% o kona ʻālohilohi, a ʻike mākou ua lapalapa ia. Hiki ke nakinaki ʻia me ka umekaumaha i nā hōkū ʻo Alpha Centauri A a me B, he 15 mika ka mamao. nā ʻāpana astronomical ((ʻāpana astronomical - ma kahi o 150 miliona km).

I nā mahina mua o 2016, ua ʻike ʻia ʻo Proxima Centauri me ka hoʻohana ʻana i ka spectrograph HARPS, e hana pū ana me ka telescope ESO 3,6-mika ma ka La Silla Observatory ma Chile. Ua aʻo ʻia ka hōkū e nā telescope ʻē aʻe a puni ka honua. ʻO ka hoʻolaha mākaʻikaʻi holoʻokoʻa he ʻāpana o kahi papahana i kapa ʻia ʻo Pale Red Dot. Ua hoʻopaʻa ʻia kahi hui o nā kilo hōkū i alakaʻi ʻia e Guillem Anglada-Eskud o Queen Mary University ma Lākana i nā loli iki o nā laina hoʻokuʻu kikoʻī o ka hōkū, ma muli o ka mea i manaʻo ʻia ʻo ka gravity. hukihuki o ka honua kaapuni.
